What they fail to state is that Provo Utah is a college town. A mormon college town. Mormons vote overwhelmingly republican. Also, most of the students in Provo come from families with ties back to mormon pioneers. Mormon pioneers were predominately white europeans. The only color you'll see in provo, besides the international students, are Hispanic and Polynesian. My family consists of both. In my ward at Church, there are only three or four other couples who aren't caucasian by definition. Most of the students here come from middle class families. That's because unless you are on a scholarship you'd generally need the financial support of a middle class family to go to college.
Correlation does not equal causality. Being middle class and white does not make provo Conservative so much as the fact that it's filled with Mormon College students who traditionally are very conservative.
The real problem here is it seems that the ghetto culture, the culture of ignorance, victimhood, and entitlement, that is perpetuated in certain black communities like Detroit is actually the result of liberalism. It isn't the color of ones skin, their financial standing, or the ghetto they live in that makes them liberal, I think it's the other way around. The liberal mentality of a complete absence of personal responsibility and moral restraint creates the drug addicted, poverty stricken, filthy ghettos which are overrun with gangs made of kids from fatherless homes and teenage mothers. In addition, the liberal desire to abdicate personal responsibility from others by throwing excuses and other people's money at problems further prevents people in these conditions from getting out by keeping them dependent and expecting handouts.
